The mineral salt production is the industry which processes the natural manure salts to extract the pure ones that are used in cooking or medicine. The raw material for this production is the sea water, the sediments of sea salts from arid zones and the lake or sea underground salt brines.

The applicative task of mineral salt production is projecting the potassuim, sodium and sulphate salts processing plants. It also projects the methods of processing the mining and chemical raw materials sch as raw rock phosphate, sodium sulphate, manure salt, brucite and magnesium carbonate. The products of processing phosphorite and potassium salts are the essential mineral fertilizer agents. Actually they are not as dangerous as are considered to be by the ecologists. If the plants lack potassium their develop slows down, their leaves and buds die back. Such plants can’t bring fruit generally but if they still bring some such fruit don’t ripe properly and can’t be stored for a long time. Potassium as well as phosphor has the positive effect on the amount of vitamin C that fruit and vegetables contain. The resistance to the wide range of various diseases is also higher if the plant gets the proper amount of potassium. The plant has stronger immune system which prevents the mycotic diseases and allows it to be more enduring which is important during the dramatic leap of the temperature levels.
